Re: VHDL to BLIF issue (LEON2)

For everybody who is interested:

It is really possible to translate VHDL to BLIF with
Altera Quartus II by enabling hidden variables in the
qsf-File of the project
(dumb_blif_before_optimize=true or
dump_blif_after_lut_map=true). But there are some
restrictions. You have to take care not to use FPGA
specific megafunctions (just take a device with no
megafunctions implemented, so i did with ALTERA MAX
II). Further BLIF cannot handle asyncronous signals,
in this case you have to rewrite your VHDL-code).
